photo-Claisen rearrangement

{
  "id": "MLC-T-CHM-008828",
  "term": "photo-Claisen rearrangement",
  "field": "Chemistry",
  "definition": "A photochemical reaction that is analogous to the thermal Claisen rearrangement, involving the light-induced migration of an allyl group from an oxygen or nitrogen atom to an adjacent carbon atom of an aromatic ring. This process typically proceeds through a radical mechanism, differing from the concerted pericyclic pathway of its thermal counterpart. It is observed in allyl aryl ethers and related compounds.",
